I Removed this in order to Remove the Carb. When I was Re-Installing This, I Broke 1 of the Breather Bolts!!! I Couldn't Find a Bolt, So I Ordered This!!!! The Breather Bolt Worked Perfectly!!! The Rest of It is Hanging on My Wall, as a Monument to My Stupidity!!!!

BEST ANSWER:The type of carburetor does not effect the fit/function of the crankcase breather kit. The only factor the carburetor has is the clearance above the cross over tube. If that becomes a factor, I just cut the tube out and run a hose/clamps between the breather fittings. Also, I prefer to not run the bottom breather hose to the air filter mount (breather oil ends up going in your intake (dirty - poor design). I run a separate (small) filter off the end of the bottom breather kit hose.

will it fit an S&S evolution engine that has no carb backing plate mount? It's the S&S engine and lack of a carb backing plate that uses the oil breathers as mounts that concerns me about the kit fitting.
